Why, you ask? Well, it's simple. You're bringing all of Hollywood's biggest names together under one roof to honor and celebrate their work, which also means that you're bringing together a lot of former lovers under one roof and forcing them to clap and smile and cheer on their ex.
It can get a little weird. And such was the case tonight at the Hollywood Film Awards, which reunited exes Kristen Stewart and Robert Pattinson. But they weren't alone. Jennifer Lopez and Ben Affleck were also there, too!
